In reply to tom_in_edinburgh:
Although it is about high altitude guiding, I like something Anatoli Boukreev said, which I think sums things up reasonably well - 'people used to prepare for the mountains, now we prepare the mountains for the people'.
I started climbing a few years ago and relatively late in life compared to many I imagine. I looked at trad and thought; too much kit, too much money; too much to learn. I carried on indoors but didn't stamp my feet and demand an indoor experience outside, it was my decision not to put in the effort.
Then a friend with many years trad experience said lets go climbing. It was a faff at first to learn but, watching someone else, using a book (took me a little longer than 10 mins!), equalising anchors from my loft hatch and now I trad climb with my wife, leading, self-sufficient, and absolutely love it.
It appears you want to encourage people outside from climbing walls but rob them of the full experience. I think that would be an absolute shame.
As for grotty quarries, I have yet to have the pleasure but, if you are climbing an existing trad line, there has to be a belay at the top somewhere, surely?
I have never top roped outdoors, don't exactly need to headpoint at my level, but building a decent anchor without bolts to do so has surely got to be considered a basic skill?
